VBS通过WMI获取CPU使用率的代码

python固然强大，但是调用wmi还是用vbs比较“正宗”。

on error resume next
strcomputer = "."

set objwmiservice = getobject("winmgmts:\\" & strcomputer & "\root\cimv2")
set colitems = objwmiservice.execquery("select * from win32_processor",,48)

for each objitem in colitems
wscript.echo "loadpercentage: " & objitem.loadpercentage
next
